' To all whom it may concern:

Be it known that we, En BnRAYMOND an Burner, of which the following 13 a specifi-- cation.

The present inventlon relates to improvementsm fluid h dro-carbon burners, the

primary ob'ect o the inventionv being the grovision 0 a fuel oil. burner adapted to be isposed upon the grate of an ordinary range, cookm stove, heating stove, hot air furnace and 0t water and steam heatm boilers, the said burner being so constructe as to be placed upon the upper surface of the grate within the fire box of the apparatus, the remaining portion of the grate surrounding the same being sealed against the admission of air through the draft doors and chimney so that the flow of air is d1- rected through the fluid hydro-carbon burner to be properly mixed with the vapors of the oil to fully consume A further object of the present mventlon produce an intensely hot and is the provision of a fluid h dro-carbon burner composed of a few num er of separa'ble parts, the same being preferably made circular in form so that the fluid hydrocarbon is admitted concentrically from below to a fluid dis ensing disk which is provided with a plurality of channels upon t face thereof and a series of concentric s ots therethrough whereb the current of a r entering from below W111 properly comnnngle with the vapors generated by the dlfi'used oil or fluid hydro-carbon uponthe upper surface of the fluid dispensing disk, the peculiar shape of s reader being d1 s osed above and .concentncallfi of the'flui d1spensing disk to direct t the i ting om the burner in the form of a circle so that the entire fire box will be properly eu per e flame caused ition of the hydro-carbon gas em1t-- current of air entering from the bottom through the annular channel and cause the same to be directed to commin le with the 'sk, a conical spreader being inverti 1y disposed with its apex above and concentrically of the fluid dispensing disk so as to guide the fluid hydrocarbon properly to the fluid dlapensing disk and at the same time provi e a means for diffusing the flame to roduce a circular flame at the upper rim of the mixing chamber of the burner.

With the foregoing and other objects in View which will appear as the description roceeds, the invention resides in the comination and arrangement of parts and in the details of constructipn hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made withs vapors generated in the flui dis ensing in the scope of what is claimed without departin from the spirit of the invention.

In t e drawings-Figure 1 is a vertical carbon burner showin the same operably connected to the grate of a stove. Fig. 2

sectional view throuih the fluid hydrois a section taken on line 2--2 of Fig. l.

Fig. 3 is a section taken on line 33 of Fig. 1. Fig. 4 is a detail perspective view of the reduced end of the flame spreader.

Referring to the drawings, the numeral 1 designates the grate bars of any form of stove, having mounted thereon a sheet metal late 2 carrying the lower rin 3 of the urner, whose flange 4 is annular y disposed to rest upon the sheet metal plate 2 and beheld in place thereon by means of the fire clay 5, said sheet metal plate 2 and fire clay 5 sealing the remainderof the grate so as to prevent the assage of air from the usual air admittin ampers throu h the .fire box or grateof t e stove to the c imne except through the openin 6 cut out of t e metal plate 2 as indicate in Fig. 1'.

Cast integrall with .the rin or base 8 of the burner are t e spiders 7 w ich properly sup ort the circular drip an 8 provided wit the upstanding rim 9, tiie said drlp pan thereby providin an annular space or air admittin channe 0 about said pan so that the air a mitted through dampers and pass ing upwardly through the be admitted tothe burner t on h the sa d annular passageway 0 so that -t e air will be conducted within the mixing chamber 21, as will presently appear.

ate bars'l will Formed concentrically of the pan 8 is a interiorly threaded boss or sleeve 10 which has secured in the lower portion thereof the oil inlet pipe 11, which is fed from a tank, (not shown), preferably by gravity, the said tank being disposed as to beslightly above the level of the fluid dispensing ,disk 13 which is supported concentrically by means of the tubular oil conveying pipe or support 12, which enters the central receptacle 14 formed in the fluid dispensing disk 13 so that the oil fed through the said pipe or tube 12 will enter the said chamber 14 and pass over the'upper rim thereof into the channels 15 and 16, of the said fluid dispensing disk 13, said channels being separated from each other by means of the ribs 17 which provide the air inlet slots 18 so that the air entering the passageway C will be conducted when in the mixing chamber beyond the peripheral edge of the fluid dispensing ,disk 13 and through the slots 18 thereof, so that the gas generated by the oil held within each of the channels 15 and 16 and the recesses 19 will be thoroughly mixed with the currents of air passing through the grate and upwardly through the burner so that by the time the said gas has been mixed and passed over the rim of the mixing chamber 21, which is supported at its shouldered portion 20 to the upper. rim of the base 3, a thor-.- oughly mixed gas isproduced, so that when ignited no soot or smoke will be apparent. The mixing chamber 21 is provided as shown with the igniting aperture 22 which is controlled by the pivoted closure 23 through which a flame may be inserted or projected to ignite the oil permitted to flow or drip within the drip pan 8 at the mounting of the I low flame in mild weather and burner.

The flame spreader 24 is preferably made cone-shaped as illustrated in Fig. 1, the apex 25 thereof being specially pointed 'as at 26 to cause the fluid hydro-carbon or oil as it enters the chamber 14 to be directed to the plurality'of channels or ducts 27 so that the same will pass through the outlet a and over I the upper rim of the chamber 14 and finally into the recesses 15 and 16 and radial slots 19 of the fluid dispensing disk 13. It will thus l be seen that this burner comprises but three separable parts. the base 3 which carrries the 1 drip pan 8 and the vertical stem 12 which supports the fluid dispensing disk 13 being one part, while the mixing chamber in re-: ality being a tapered open ring 21, being: another part, whilethe spreader 24 is the; third, thus providing an exceedingly siniple and inexpensive burner and one which may be readily removed to be cleaned, that is, when 1t is desired'to clean the same the spreader 24 is removed. first, and with a brush may be cleaned of the soot or any other products of combustion collecting thereon, the removal of the spreader 24 permitting the mixing chamber or ring 21 to be moved upwardly and from about the fluid dispensing disk 13, thus exposing the said fluid dispensing disk and drip pan so that the same may be brushed and properly cleaned;

When it is desired to light the burner, it is simply necessary to open a valve, not shown, so that the flow of oil or fluid hydrocarbon through the pipe 11. may be controlled to a nicety according to the heat desired to be generated. This action permits the oil to flow into the channels of the fluid dispensing disk 13 and to drip therefrom into the drip pan 8; When the lower surface of the drip pan 8 has been covered with the oil, the closure 23 is moved to permit the introduction of a flame through the aper ture 22 to ignite the oil both in the drip pan 8 and in the channels of the fluid dispensing disk 13. When-the oil has sufliciently burned to produce the desired heating of theparts'of the burner, the valve is again turned on and the oil admitted through the stem 12 into the channels of the fluid dispensing disk 13 will become ignited, the regulation of the flow of air through the passageway G into the mixing chamber and around the fluid dispensing disk 13 being controlled entirely through the means of the regular stove dampers, so that the flame produced and diffused from the upper rim of the mixing chamber 21 y will be according to the amount of air and oil supplied. By this means it is evident that the flame may be readily .centrolled to attain heat for various purposes when cooking and when used in heating stoves or fur. naces, the same may be controlled to have a a high flame in cold weather. 7

The burner is preferably made of cast iron, and as illustrated .in Fig. 1, is readily placed in operable position by any mechanic,- it simply being essential that the grate be sealed entirely except at the opening 6, as

indicated in Fig. 1, so that the air is d1 rected entirely within the mixing chamher 21 of the burner to be properly mixed with the vapors due to the rising temperature'effeet 4 upon the hydro carbon fluid or oil within the grooves or recesses of the fluid dispensing disk 13. g What is claimed is:

1. A fluid hydro-carbon burner, havingan annular base, a concentric drip pan carried thereby and providing therewith a plurality of peripherally disposed air admitting ports, a concentrically pipe projecting upwardly from the drip pan, a fluiddispensing disk provided with a concentric chamber, the upper rim of which terminates above the upper surface of the disk and in communication with the upper 'end of the oil'feed pipe, a tapering rmg disposed oil feed .the fluid dispensing disk.
